IMPROVEMENT IN SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 19,871, dated April 6, 1858.

T0 all whom it may concem:

Be it known that I, THOMAS A. RISHER, of Circleville, county of Pickaway, and State of Ohio, have invented certain new and useful Improvements in Sceding-Machines; and I do hereby declare that the followin g is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement of certain devices, the peculiaritics of which will be hereinafter described.

In order that others skilled in the arts may make and use n1y machine, I will procecd to describe its construction and operation.

In the annexed drawings, making a part of this specification, Figure 1 is. a bottom View of the seed-hopper. Fig. 2 is a longitudinal vertical section.

In Fig. 1, A represents the seed box or hopper. F F are metallic ears or plates, secured to the hopper for the pnrpose of securing the machine to the carriage. B B B B are four metallic bars, secured to the bottom of the hopper by means of the screws e e. Said screws, passing through the slots d d of said bars, allow of their being adjusted to suit the quantity of grain to be distributed. c c c 6 are plates forming a part of the bars B B B B m n are projections secured to the bars B B B B The right and left screws E E, being secured to the hopper, pass thr0ngh these projections, and are the means of.operating the bars B B B B. G G are levers secnred to the slides of the machine, and serve to operate them and connect them with the running-gear of the carriage.

In Fig. 2, B B are the bars seen in Fig. 1. E E are right and left screws for the purpose of regulating said bars. m m n 92 are projections, secured to said bars, and through which screws E E pass for the pnrpose of adjusting the bars. a is the inside bottom of the hopper. a a are the reciprocating slides for the purpose of carrying the se ed. 0 is a stirrer, passin g through the hopper, for the purpose of agitating the grain to prevent elogging or choking. Said stirrer, beingin the I'orm shown inthis figure, is secured to the slide a, and is operated by means of it when the machine is in motion.

The bars B B B B in this machine are made in four parts, as will be readily seen, and are so constructed in order to avoid the irregularitics of the cast slides and for the pnrpose of arriving at a nicer and more regular adjnstment of said bars to suit the quantity of seed v to be discharged.

It will be seen that as the plates c c c 0 are made to approach each other the apertures are made smaller and a less quantity of seed may be discharged, and that when they recede from each other a greater quantity of seed will be discharged. Now, in casting the slides a a, if one slide is cast a very little thieker than the other, the cnps of that slide will bejust that much deeper, and if all the plates were regalated alike one side of the machine would seed much more totheacrethan tlwothrrsidewould; but by providing a set et plates and a screw for each slide I am enabled to rvgnlate these plates te suit the thickness of the slide, and

thus make my machine seed alike at all times.

Having thus fnlly described my invention, I do not claim the combination of the bar and plates with the donbleholed bottom and the reciprocating slides, as this I have patented;

but

What I do clai1n is The peculiar arrangement of the bars B B B B with the ri ght and left screws E E, slides a and (1, with its stirr'er 0, for the purpose et regulating thequantity ot' grain With uneven slides, as is herein fully desoribed.
